Context

“Such is every despotism, the constitution of most Mohammedan kingdoms; and indeed various parts of many constitutions are also of this kind; for example, serfdom, vassalage, and many such institutions. The pure theory of right or natural right—better, moral right—though always reversed, lies at the foundation of every just positive legislation, as pure mathematics lies at the foundation of every branch of applied mathematics. The most important points of the doctrine of right, as philosophy has to supply it for that end to legislation, are the following: 1. The explanation of the inner and real significance both of the origin of the conceptions of wrong and right, and of their application and position in ethics.” source
